All eight drug tests conducted at UFC
144 came back negative, according to UFC Vice President of
Regulatory Affairs Marc Ratner.

Sherdog.com confirmed the results Tuesday with Ratner, who verified
that headliners Benson
Henderson and Frankie
Edgar tested negative for both performance enhancing drugs and
drugs of abuse. Six randomly selected competitors also produced
negative tests at the event, which took place Feb. 26 at Saitama
Super Arena in Saitama, Japan.

When holding events in the United States, the UFC defers to state
athletic commissions to conduct drug testing of its fighters.
However, when promoting shows in countries that lack such
regulatory bodies, Ratner oversees the process, hiring independent
agents to conduct the tests.

Former World
Extreme Cagefighting champion Henderson wrested away Edgar’s
UFC lightweight title in the main event, besting the New Jersey
native in a five-round unanimous decision. Edgar was granted an
immediate rematch, and the pair will fight over the gold once again
later this year.

Also of note, Sherdog confirmed with Ratner that all 24 competitors
were tested at Saturday’s
UFC on Fuel TV 2 in Stockholm, which was overseen by the
Swedish Mixed Martial Arts Federation. Test results should be
available sometime next week.
